ABSTRACT. Records of shoreline and bluff positions in the vicinity of Barrow, Alaska, have been obtained from aerial photographs and taped measurements for intervals between 1948 and 1969. Although the source material in the bluffs is frozen and masses of pure ice are present, temperature and rainfall data fail to show any marked correlation with the retreat of the bluff face or with the retreat of the fronting or downdrift beaches. Removal of beach material for construction and frequency of storms from the west do show a relationship. Recorded retreats of the bluffs up to 3 m. per year and of the beaches up to 4 m. per year have resulted where there has been excessive beach borrow or where a series of severe storms have attacked the coast. RÉSUMÉ. Changements climatiques d court erme et érosion côtière, Barrow, Alaska. Entre 1948 et 1969, à partir de photos aériennes et de levés sur le terrain, les auteurs ont recueilli à intervalles des données sur la position du rivage et d'es-carpements au voisinage de Barrow, Alaska. Bien que le matériel des escarpements soit gelé et truffé de masses de glace pure, les données de température et de pluie
